Clarifying Questions (3 minutes)

• Looking at the scale, I'm thinking this might be a systemic issue. Can you confirm if this 30% is consistent across all user segments and transaction types?

Why it matters: Understanding the scope helps narrow down potential causes. Expected answer: It's relatively consistent across segments. Impact on approach: If consistent, we'd focus on system-wide issues; if not, we'd investigate specific segments.

• Considering timing, I'm wondering if there have been any recent updates to the reward system. Have there been any changes to the points calculation or crediting process in the last 30 days?

Why it matters: Recent changes often correlate with new issues. Expected answer: A minor update was pushed two weeks ago. Impact on approach: If confirmed, we'd prioritize investigating that update.

• Thinking about data integrity, I'm curious about our monitoring systems. Are we confident that the 30% figure is accurate, and not a result of reporting errors?

Why it matters: Ensures we're solving a real problem, not a data anomaly. Expected answer: The figure has been cross-verified from multiple sources. Impact on approach: If uncertain, we'd first validate our data collection and reporting systems.

• Considering user behavior, I'm wondering about the visibility of this issue. Are we seeing an increase in customer support tickets or app store reviews mentioning missing points?

Why it matters: Helps gauge the user impact and urgency of the situation. Expected answer: There's been a 20% increase in related support tickets. Impact on approach: High user awareness would prioritize quick, visible fixes alongside root cause analysis.
